试验比较了~(60)Co—r 射线辐照、气调、药剂等保鲜方法对双孢蘑菇保鲜的效果,得出以纸塑袋密封包装,加天然去异味剂,采用自发气调法保鲜,效果最佳。在5℃左右温度条件下可以保存10—15天,开伞率不超过3%,基本无褐变和异味,失重率在2%以内,质地基本不下降。同时,研究了自发气调保鲜的作用机制,证明自发气调保鲜法,氧与二氧化碳分压可分剐调整到2—3%和10—15%,在这种条件下,多酚氧化酶的活性明显下降。
The experiment compared the effect of ~ (60) Co-r radiation irradiation, modified atmosphere, medicine and other preservation methods on the preservation of Agaricus bisporus, obtained sealed packaging with plastic bags, added natural deodorants, , The best effect. The temperature can be stored at about 5 ℃ for 10-15 days, the opening rate does not exceed 3%, basically no browning and odor, weight loss rate of less than 2%, the basic texture does not decline. At the same time, the mechanism of spontaneous atmosphere preservation was studied. It was proved that spontaneous atmosphere preservation method, partial pressure of oxygen and carbon dioxide could be adjusted to 2-3% and 10-15%. Under this condition, polyphenol oxidase Activity decreased significantly.
